Dear Huiqi, I can be a problem related to MTU. From IPSO 3.8-build 049 can lower the MTU. Nokia suggest a value of 1400 (Nokia Knowledgebase: Vantive Resolutions ID: 1128905).
Hope this helps, Christian -----Ursprüngliche Nachricht----- Von: Mailing list for discussion of Firewall-1 [mailto:[EMAIL PROTECTED] Im Auftrag von Huiqi Liu Gesendet: Mittwoch, 30. Juli 2008 09:59 An: [email protected] Betreff: [FW-1] Strange problem Sorry I can't be more specific on the subject line! Recently we have set up a new branch office firewall, with a Nokia IP130, running NG AI R55p, IPSO 3.8, with ADSL connection (PPPoE) to the internet. There are about 10 users in the office who are connected a switch which connects to an interface on the Nokia. We have set up VPNs between that office and other locations, and that works fine. The problem is: Since the firewall install, 5 or 6 laptops have these problems: Accessing certain websites (e.g., microsoft.com, and some other sites, e.g., www.sina.net) Accessing MSN Accessing Hotmail Intermittent problems accessing pop3 email using Outlook Express 2 users don't have any of the problems above. And the curious thing is that these two users were in the office with their laptops when the changeover occurred, though there is a desktop in the office at the same time but that has the same problems above. Before the firewall was installed, the switch was connected directly to the ADSL router, and there were no such problems. The firewall logs all look fine: outgoing requests from the problem laptops were shown to be accepted like the rest. I'm really lost as to what might have caused these. Any ideas would be much appreciated!
